Which ratio is NOT equivalent to the other choices?

A) 5:9

B) 9:5

C) 5 to 9

D) 5/9 (fraction)

9:5

Step-by-step explanation:

Because 5:9 = 5/9

9:5 = 9/5

5 to 9 = 5/9

5/9 = 5/9

So, 9:5 is the odd one out

Answer B is not equivalent to the other choices because answer A, 5:9 as a fraction is 5/9 and answer C as a ratio is 5:9 and as a fraction 5/9 and answer D as a ratio is 5:9. But, answer B is 9:5 which is 9/5 and not equivalent to 5/9.
